OAR-LOCK.

SPECIFICATION formingpart of Letters Patent No. 71 1,469, dated October 21, 1902.

Application filed May 16,1902.

. gan, have invented certain new and useful Improvements in Oar-Locks, of which the following is a specification.

This invention relates to improvements in rowlocks. It is particularly adapted for use on metal boats having a double rail-that is,

an inner and outer rail, like that shown in Patent No. 681,363, of August 27, 1901, to Arthur E. Ohambersthough it proves satisfactory in other structures.

a The objects of the invention are to provide a simple and efficient rowlock which is easily and quickly attached and is not liable to loosen with use or shrinkage and one which, if this occurred, can be quickly tightened. Other objects will definitely appear in the detailed description to follow.

We accomplish the objects of our in vention by the devices and means described in this specification. Y

A structure embodying the features of our invention is fully illustrated in the accompanying drawings, forming a part of this specification, in which-- Figure 1 is a detail longitudinal section of an oar-lock embodying the features of our invention illustrated in position on a boat, taken on line 1 l of Fig. 2. Fig. 2 is a detail cross-sectional view of the same, taken on line 2 2 of Fig. 1. Fig. 3 is a detail perspective view of a rowlock embodying the features of our invention in an inverted position.

In the drawings all of the sectional views are taken looking in the direction of the little arrows at the ends of the sectionlines, and similar letters of reference refer to similar parts throughout the several views.

Referring to the lettered parts of the drawings, A represents the wall of the boat, and A the ribs.

B B are the inner and outer rails, all of which may be of the usual construction.

0 is the body portion of the rowlock, which is preferably formed hollow to secure lightness of the same.

0 is a suitable opening to receive the lock- Serial No. 107,562. (No model.)

loose, and should this occur it may be quickly and easily tightened. It will be noted that the pull of the oar comes squarely on the fastenings and does not have any leverage thereon, as occurswhen the locks are secured to the side of the rail.

We have illustrated our improved oar-lock specifically in the form which we believe to be preferable. We are aware that it is capable of structural changes without departing from our invention.

Having thus describedour invention, what we claim as new, and desire to secure by Letters Patent, is-

1. In an oar-lock, the combination of abody portion C, adapted to rest on the rail of a boat and having an upwardly-projecting portion 0, adapted to receive the pintle of an oar; and the downwardly-projecting, centrally-located lugs C 0 adapted to pass between the rails of a boat and suitably perforated to receive retaining-bolts whereby the rails are clamped upon said lugs, for the purpose specified.

2. In an oar-lock the combination of a suitable body portion adapted to receive the pintie of an oar and to rest on the rails of a boat;

and having downwardly projecting perforated lugs adapted to pass between the rails of a boat and be clamped between the same, as specified.

In witness whereof we have hereunto set our handsand seals in the presence of two witnesses.
